Product Description

Pericom Semiconductor?s PI74LPT series of logic circuits are produced using the Company?s advanced 0.6 micron CMOS technology, achieving industry leading speed grades.

The PI74LPT240 is an 8-bit inverting buffer/line driver designed for driving high-capacitive memory loads. With its balanced-drive characteristics, this high-speed, low-power device provides lower ground bounce, transmission line matching of signals, fewer line reflections and lower EMI and RFI effects. This makes it ideal for driving on-board buses and transmission lines.

The PI74LPT240can be driven from either 3.3V or 5.0V devices allowing this device to be used as a translator in a mixed 3.3/5.0V system.
